Should probably do this over on one of the TV forums but coming at it from the bottom up here. :-) I've got a satellite TV receiver that can be configured for 4:3 and 16:9 aspect ratios. Video outputs are RF (Ch 3 or 4), composite video? (RCA jack) and S-video. When you change the aspect ratio of an analog TV signal does it keep the same number of scan lines and cram more "pixels" on each line? Would all of the analog connectors above support the different ratios or would some only support 4:3? thanks -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
